0<= x<= 1
You have the following 2 equations:
[1]: 0 <= x
[2]: x <= 1
Solution found [1]: x => 0
Solving for x: x <= 1 [2] where x => 0
Let's build the table of the different terms to determine the global solution:
x-∞ 0 1 +∞
x => 0❌✅✅✅✅
x <= 1✅✅✅✅❌
Global solution❌✅✅✅❌
▶Solution obtained [2]: x ∈ [0, 1]
